Marginal Revolution is an extremely popular economics blog co-authored by Tyler Cowen and Alex Tabarrok, both of whom are professors of economics at George Mason University. Posts are mostly brief, usually containing an excerpt from an article or blog post published elsewhere with a brief comment from Cowen. It’s a economics focused blog but everyone will find something they like. Cowen’s “Assorted Links” posts contain a smattering of interesting links from the day like this one explaining why trees don’t want to touch each other and and this article on the National Valet Olympics. Also, the comments section isn’t completely useless.
